The International Motorcycling Federation has updated its homologated model list for the 2013 World Superbike, Supersport, Superstock and Endurance racing seasons. The list is largely unchanged from the list released in February with the exception of a couple of additions.

The Superstock 1000 and Formula Endurance World Championship list now includes the 2013 Ducati 1199 Panigale R and the MV Agusta F4 RR. On the previous list, the F4 RR’s status was listed as being “in progress” while only the S version of the Panigale was initially homologated for Superstock 1000 and Formula Endurance.

Also worth emphasizing is the 599cc Kawasaki Ninja ZX-6R remains homologated for the FIM’s Supersport and Superstock 600 championships but the 636cc version is not eligible for those classes. The homologation list distinctly includes the Ninja as the “ZX 600 R F” but not “ZX 636″. AMA Pro Racing differs in this regard, including the 636cc version on its list of eligible racebikes for 2013.
